Title: "The Lonely Moon" Speaker: Michael Lennick, Writer/Director Foolish Earthling Productions.  45 years ago, humanity set foot on the moon. Three and a half years later we stopped going and haven't been back since. The obvious question is, why?

City Star Party

Hover above the moon like an astronaut and get eye-to-eye with the planets. Find colourful stars, star clusters, bright nebulae and even another galaxy. Our monthly City Star Party is the place to catch universe from within the city limits at Bayview Village Park. If you don't have a telescope then you will find many astronomers who would love to share a view. If you are thinking of buying a telescope, viewing with other people's equipment is the best way to make a good choice. If you have a telescope or binoculars, please bring it!

Dark Sky Star Party

See the Milky Way and galaxies with the unaided eye. Point your telescope to find the many dim deep space objects that sprinkle the sky. Away from Toronto's light pollution, there is so much to see. We observe from the Long Sault Conservation area, an hour outside of Toronto. We meet around dusk once a month in the parking lot for views only seen in dark sky conditions. We hold this event on the first clear night of our week-long window, so the date and time are determined closer to.

New Moon

The moon is between us and the sun. Without the moon in the sky at night, deep sky objects are easier to observe.
